Does anyone know any kid geniuses?

I’m friends with an incredibly smart kid. He’s 14, but has been put up three grades in school at one point. He does all the obvious enrichment things which are available in the relatively small Australian city he lives in.

His life experience has been pretty unusual. He doesn’t really know what it’s like to be challenged in school. All his friends are way older than he is. (Once, I asked him how being constantly around people older than him made him feel. He replied, “Concerned for my future.”)

He doesn’t know anyone like him, which I think is a shame: he’d probably get along very well with them.

Does anyone know any similar kid geniuses? If so, can I give them my friend’s details?

Thanks.
